How to Choose GRC Decorative Panels in Guangzhou in 2026? Watch These 5 Hard Metrics

In 2026, Guangzhou's urban construction is accelerating across the board. From the conclusion of the "14th Five-Year Plan" to the opening of the "15th Five-Year Plan", from Zhujiang New Town to Nansha New Area, and from urban renewal to "good housing" construction, Guangzhou's quality requirements for building facades are reaching new heights. With advantages such as light weight, high strength, flexible shaping, and A1 fire rating, GRC (glass fiber reinforced cement) decorative panels have become the ideal material choice for the facades of high-end residences, commercial complexes, and landmark buildings in Guangzhou.

However, Guangzhou is located in a subtropical monsoon climate zone with high temperature and humidity, frequent typhoons, and severe salt fog corrosion, which place extremely stringent demands on the weather resistance, wind pressure resistance, and durability of GRC decorative panels. When buying GRC decorative panels in Guangzhou in 2026, how exactly should you choose? I will break it down for you one dimension at a time across five aspects.

I. Three Special Requirements for GRC Decorative Panels in the Guangzhou Market

As the core city of the Guangdong-Hong Kong-Macao Greater Bay Area, Guangzhou's building standards have always been at the forefront of the country. In 2026, Guangzhou has put forward three special requirements for GRC decorative panels:

First, the durability test under a hot and humid climate. Guangzhou has high temperature and humidity in summer, warm and humid winters, and frequent typhoons, while coastal areas also face salt fog corrosion. GRC decorative panels must offer excellent impermeability, freeze-thaw resistance, and chloride ion penetration resistance. The flexural strength of outdoor weather-resistant GRC components should be no less than 16MPa, and the compressive strength should remain stable within the 40-60MPa range to meet the long-term structural stability requirements under South China's hot, rainy conditions and coastal salt fog corrosion. High-quality GRC can withstand more than 300 freeze-thaw cycles.

Second, the policy orientation toward green building materials. Guangzhou has issued a series of policies such as the "Implementation Plan for the Government Procurement Policy of Supporting Green Building Materials to Promote Building Quality Improvement" and the "Regulations on the Administration of Green Buildings and Building Energy Efficiency", and green building material procurement has become a mandatory requirement for government-invested and state-owned projects. Guangzhou has also launched a collection of applicable building material products for "good housing" construction, promoting the widespread application of green building materials in construction projects across the city. As a green and environmentally friendly building material, GRC is entering a policy dividend period.

Third, the quality requirements of landmark-level projects. From the Guangzhou Chow Tai Fook Financial Centre (530 meters) to Guangzhou Xinghewan, and from Guangzhou Dongzhu Shangdu Commercial City to the American International School of Guangzhou, Guangzhou's projects demand top domestic levels of precision, strength, and artistic expression for GRC decorative panels.

II. When Buying GRC Decorative Panels, Focus on Five Hard Indicators

Hard Indicator 1: Flexural Strength — The Core Lifeline

The strength of GRC decorative panels directly affects building safety and service life. High-quality GRC should have a flexural strength of 20MPa or above and a density ≤1800kg/m³, achieving lightweight design while ensuring strength. Thin GRC decorative panels (thickness ≤15mm) also need a flexural strength ≥12MPa. When purchasing, be sure to request third-party test reports to verify flexural strength data. Fiber content is the key factor determining strength — high-quality GRC products have a fiber content ≥5%.

Hard Indicator 2: Weather Resistance and Anti-Aging Capability

Guangzhou's hot, humid, and rainy climate places extremely high demands on GRC's weather resistance. After accelerated aging tests, the performance degradation rate of high-quality GRC should be controlled within 15%. At the same time, attention should be paid to durability indicators such as freeze-thaw resistance (≥300 cycles without damage is recommended), impermeability grade, and chloride ion penetration coefficient. Sampling tests on the Guangzhou Xinghewan project showed that Qinglong GRC components still achieved an impact strength of 18kJ/㎡ after 10 years of use, 20% above the standard value.

Hard Indicator 3: Fire Rating — The Safety Baseline

As a cement-based material, GRC has natural fire protection advantages. High-quality GRC decorative panels should meet the Class A non-combustible material standard, fully complying with building fire code requirements. According to tests under the GB8624-2012 standard, the combustion performance grade of high-quality GRC products can reach A2, and the smoke toxicity grade can reach AQ1. In large commercial complexes such as Guangzhou Dongzhu Shangdu Commercial City, the GRC curtain wall system is designed in coordination with fire-stopping construction, forming a complete fire barrier.

Hard Indicator 4: Surface Treatment and Decorative Effect

The advantages of GRC decorative panels lie not only in performance but also in artistic expression. When purchasing, pay attention to surface treatment processes — the realism of stone-like textures and the jointing tolerance of special-shaped components (recommended within ±2mm). The reproduction precision of surface textures needs to be verified through 3D scanning comparison, with a match rate of no less than 95% against the sample; color deviation should meet the CIE LAB color space △E≤3.0 indicator to ensure no color difference between different batches. For perforated decorative GRC panels, structural safety also needs to be verified as a priority.

Hard Indicator 5: Construction Adaptability and Technical Support

No matter how good the material is, if the installation process cannot keep up, the results will be greatly diminished. When purchasing, examine the manufacturer's installation techniques — do they use a dry-hanging system? Are they equipped with a three-dimensionally adjustable anchor system? Can installation precision meet standards? More importantly, check whether the manufacturer can provide full-chain technical support from detailed design, BIM modeling, and manufacturing to on-site installation guidance. Qinglong's modular installation process achieves "zero-error" jointing.
